Application filed ma 22,

To aZZ whom it may concern:

Be it known that I, E. Bonnrr, a citizen of the United States, residingin Chicago, in the county of Cook and State of Illinois, have invented anew and useful lmprovement in Printing-Press Joggers, of which thefollowing a specification.

This invention relates in general to printing presses and has moreparticular reference to the provision of means for insuring accurateplacement of the printed sheets upon the press table as they aredelivered to it by the fly.

The invention has for its object broadly the provision of accurately andpositively operating means for holding the delivered sheets upon thepile as they are deposited by the delivery mechanism.

The invention has for a further object the provision or means foraccomplishing this result which will not interfere in any man nor withthe normal and heretofore usual action of. the mechanism for deliveringthe printed sheets, and which will act to restrain any tendency thesheets may have to follow the delivery mechanism on its returning oridle stroke.

Still another important object of the in vention is the provision ofmeans of this character which may be provided as a mere attachment,consisting of a small number of simple parts, adapted for easyinstallation on printing presses already in use and this withoutrequiring any reformation, replacement or readjustment of the parts ofthe press, and which may be readily adjusted for operation on sheets ofvarious sizes.

Another object of the invention is the provision of an apparatus of thecharacter described of simple, sturdy construction, the parts of whichwillnot require frequent repair or replacement, and which, bemg whollyautomatic in its action, will not require the constant attention of thepress operator.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

For the purpose of illustrating my present invention 1 have shown on thedrawings so much of a printing press as is believed necessary to anunderstanding of it. Reference character 11 represents one of the crossrods or braces of the press frame, reference character 12 a shaftcarrying the pul leys or spools 13 for the tapes 14. Reference character1! indicates the oscillating shaft for the flies 16 adapted to lift thesheets from the tapes and deposit them in a pile upon the presstablelocated between the table rails 17. it will be understood that the mainfly 16 moves in a counter-clockwise direction (viewing Fig. 2) in itsoperative stroke and in the reverse direction n its inoperative stroke.

in the present instance l provide an auX- iliary or oppositely actingfly to insure that the deposited sheets are held against movement withthe mainfiy on its return stroke. While in the present embodiment of theinvention it may be considered a mere attachment to the printing press,it can be incorporated as a. part of its original construction and inany event cooperates with parts thereof.

This auxiliar fly comprises a shaft 18 pivoted in bearing 19 of clamps21 adapted to be fastened upon the table rails 17. At the end of theshaft at the top of Fig. 1 a spring 22 is provided having one end 23fixed in the adjacent bearing 19 and the other end 24 fixed in a collar25 locked to the shaft by set screw 26. Fly arms 27 in any appropriatenumber are mounted on the shaft and locked against independent movementby set screws 28.

This auxiliary fly is normally held down upon the top of the pile ofsheets by the spring 22 and means are provided for mov ing it back in aclockwise direction, viewing Fig. 2, when the main fly is to deposit asheet upon the pile. This means in the present instance is operated bythe main fly. An arcuate member 29 is clamped upon the shaft 15 and inposition to engage a latch 31 pivoted upon an arm 82 in turn pivoted at38 upon a collar 3-1 clamped about the frame part 11. The tail part ofthis latch engages the body of the arm when the arcuate member 29 ismoving downwardly and rearwardly viewing Fig. 2, causing the arm to movein a clockwise direction during the operative movement of the fly. Thearm 32 has an upstanding part 86 pivoted at 37 to a rod 38 which rodextends over above the shaft 18 and is connected with an arm 39 fixed onsaid shaft 18. The con nection between the arm 39 and the rod 38 isthrough a block 41 having a pivot 42 disposed through the arm 39 so thatthe parts may move freely in action. A collar 43 is fixed on the rot. 38beyond the block 11 so that when the arm 82 is actuated toward the rightviewing Fig. 2, movement of the rod 38 swings the auxiliary fly up andout of the way of the paper on the main fl The lifting movement of theauxiliary fly moves in accordance with the movement of of the main flyand when the arm 82 is moved back about its pivot 33 sufficiently topermit the arcuate member 29 to clear the latch 31, the spring 22 causesthe auxiliary fly to move back quickly into place. This action occursjust as the paper is placed upon the pile and when the main fly moves onits idle stroke the upper end of the arcuate member tilts the latch andpasses it so that the parts again assume their normal positions. A fixedstop 4A is provided upon a collar 45 fast on the shaft 18 by set screw46 which stop 4 is adapted to engage a rod 47 mounted in the bearings19. A spring stop 48 is provided to prevent too great movement of thearm 32 toward the left,

viewing Fig. 2, said stop being positioned upon the collar 34.

It will be noted that the auxiliary fly is out of position at the timeeach sheet is actually placed on the pile and comes quick- 1y downthereagainst at the moment it is deposited so that it holds the sheetbefore it has been misplaced through tendency to follow the main fly onits return movement.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing without further description and itwill be apparent that various changes may be made in the form,construction and arrangement of the parts without departing from thespirit and scope of the invention or sacrificing all of its materialadvantages, the form hereinbefore described belng merely a preferredembodiment thereof.
